Does a room humidifier help with dry sinuses/nose associated with sjogrens? what are the pros and cons of cold vs warm mist units

Keep mucosa moist: Usually oral and eye dryness is the problem. If nasal dryness is symptomatic you can try humdifier and apply vaseline inthe nastril at night to prevent the drying. You may also try the warm mist unit in cold weather. There is nothing right or wrong management

Humidifier: Anything that moistens mucus membranes will be helpful. Humidifier is a great tool. Not much difference between cool mist or lukewarm mist humidifier, more so the matter of preference and comfort. I like lukewarm slightly better, though.
